Positioning structure for holding optical disk drive and electronic device using the same

Abstract

A positioning structure for fixing an optical disk drive includes a case and a tray. The case includes a support plate and a cover located on the support plate, a receiving cavity is defined between the support plate and the cover. A groove is defined in the support plate. The tray includes a sidewall and a fixing portion located adjacent to the sidewall. The fixing portion includes a clasp portion, and the clasp portion is received in the groove.

What is claimed is: 
     
         1 . A positioning structure for holding an optical disk drive, the positioning structure comprising:
 a case comprising a support plate and a cover located, on the support plate; a receiving cavity defined between the support plate and the cover; and a groove defined in the support plate; and   a tray slidably received in the receiving cavity, the tray comprising a sidewall and a fixing portion located adjacent to the sidewall;   wherein the fixing portion includes a clasp portion, and the clasp portion is received in the groove.   
     
     
         2 . The positioning structure as claimed in  claim 1 , wherein the tray further comprises a bottom plate connecting to the sidewall, and the fixing portion extends from an edge of the bottom plate and is parallel to the sidewall. 
     
     
         3 . The positioning structure as claimed in  claim 2 , wherein the fixing portion comprises an elastic portion, a connection portion, and a extending portion; the connection portion is perpendicularly connected to the elastic portion, the extending portion is perpendicularly extended from the connection portion; the elastic portion and the extending portion are parallel and offset to each other; and the clasp portion is located on a surface of the elastic portion and extends along an opposite direction than that of the extending portion. 
     
     
         4 . The positioning structure as claimed in  claim 3 , wherein the support plate includes a first stopper portion and a second stopper portion that are opposite to each other, and an entrance is defined between the first stopper portion and the second stopper portion and is in communication with the receiving cavity. 
     
     
         5 . An electronic device, comprising:
 a case comprising a support plate and a cover located on the support plate, a receiving cavity defined between the support plate and the cover, a groove defined in the support plate;   a tray slidably received in the receiving cavity, the tray comprising a sidewall and a fixing portion located adjacent to the sidewall; and   an optical disk drive mounted on the tray;   wherein the fixing portion includes a clasp portion, the clasp portion is received in the groove.   
     
     
         6 . The electronic device as claimed in  claim 5 , wherein the tray further comprises a bottom plate connecting to the sidewall, the fixing portion is extended from an edge of the bottom plate and is parallel to the sidewall. 
     
     
         7 . The electronic device as claimed in  claim 6 , wherein the fixing portion comprises a elastic portion, a connection portion, and a extending portion; the connection portion is perpendicularly connected to the elastic portion, the extending portion is perpendicularly extended from the connection portion; the elastic portion and the extending portion are parallel and offset to each other; the clasp portion is located on a surface of the elastic portion, and extends along a reverse direction relative to the extending portion. 
     
     
         8 . The electronic device as claimed in  claim 7 , wherein the support plate includes a first stopper portion and a second stopper portion opposite to each other, an entrance is defined between the first stopper portion and the second stopper portion and is in communication with the receiving cavity.
